bug#21695: 25.0.50; Change most occurrences of `setq' in Emacs manual to `customize-set-variable'? Really?

Both would be most unwelcome here.  I often use `setq' in short "init"
files for debugging purposes and sometimes use `setq' via M-: during
debugging.  In neither of these cases I wanted to be disturbed by any
warnings.  I would, however, welcome being warned when a user option is
overridden by a package I load, either by a local binding or `setq'.  At
compile time.
